Abstract Histological and Immunohistochemical studies were carried out to document the possible impact of heavy metal contamination in different tissues of Chanos chanos. Heavy metals such as Cu, Pb, Zn, Cd, Mn and Fe were predominant in water, sediment and biota of Kaattuppalli Island and varied significantly between two different sites. Histological changes such as swelling of muscle fiber and break down of muscle bundles were noted in the muscle. Similarly gill filament cell proliferation, increase in intercellular spaces and primary and secondary lamellar epithelium were evident in gills. The hepatocytes showed damage of central vein and rupture of irregular hepatic plate with more number of vacuoles in the fish collected from polluted site compared to that from the less polluted site. The impact of pollution was also assessed in different tissues by immunohistochemistry using primary antibody (mouse monoclonal HSP70 antibody 1:2000) and secondary antibody (HRP conjugated antibody) for expression of stress protein. Immunostaining analysis showed expression of HSP70 with high intensity in the tissues of fish collected from polluted site compared to less polluted sites. Further, HSP70 positive cells were analyzed from six locations per fish tissue section. One-way analysis of variance (ANOVA) followed by least significant difference (LSD) was used to check if the expression was significant. Results indicate that the values are statistically significant at the two different sampling sites (P<0.05). Copyright © 2011 Elsevier Ltd. All rights reserved.
